The hot iron rich debris from the cutter will disperse very effectively and embed in the the fibreglass, later manifesting their presence as rust spots. Even in this enclosed spot - cover the cockpit well and consider your neighbours too
I recently cut my coupling off using a reciprocating saw - took about 10 minutes, frequently stopping to make sure I didnt damage the shaft
No sparks like a grinder and much more controllable
